Abstract

L'invention concerne un système 1 de traitement de boues huileuses qui comprend : un séchoir 3 de fermentation sous vide dans lequel des boues huileuses sont contenues dans un récipient fermé et agitées sous pression réduite tout en étant chauffées dans une plage de température définie et, en même temps, des matières organiques dans les boues huileuses sont décomposées à l'aide d'un micro-organisme, l'humidité est évaporée à partir de celui-ci pour donner une matière séchée ayant un volume réduit ; un filtre 4 destiné à filtrer une huile dans la matière séchée ; et un dispositif de lavage 5 destiné à laver à la vapeur la matière séchée à partir de laquelle l'huile a été filtrée.
